If you're going on vacation and are worried about your plants drying up, you can place a garbage bag over them to keep them temporarily hydrated.

We've already shown you several ways to keep your plantswatered and hydratedwhile you're away, but using a garbage bag is the quickest and easiest way we've seen, turning the area into a mini, self-sustaining greenhouse. Obviously, you'll want to use clear garbage bags so that sunlight can still enter through, and it's even a good idea to stick a wooden dowel rod in the planter so that the garbage bag doesn't touch the plant. For smaller plants, you can use plastic bags from the grocery store, or just use one large garbage bag for multiple, smaller plants.
